CAR BRAKE. AND STARTER.

SPECIFICATION forming part of Letters Patent No. 395,461, dated January1, 1889.

Application filed September 5, 1888. Serial No. 284,613. (No model.)

To all 207mm it 12711, concern.-

Be it known that 1, JOHN B. SWAIM, of Newborn, in the county ofBartholomew and State of Indiana, have invented a now and Improved (arBrake and Starter, oi? which the following is a full, clear, and exactdescription.

This invention relates to an improvement in car brakes and starters, andhas for its object to provide a car brake and starter which is simple inconstruction and effective in operation.

The invention consists in a car brake and starter constructed andarranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar ligu res of. r ,t'erence indicatecorresponding parts in all the figures.

liigure 1 is a plan view of the invention. Fig. 2 is an end view of theinvention with parts in vertical section. Fig. 3 is a side view invertical section on the line ma, Fig. 2. Fig. 4 is a side view invertical section on the line y 1 2; and Fig. 5 is a side view invertical section on the line .2 z, Fig.

In carrying out this invention a disk, 1, is rigidly mounted on the aXle2 of a car, and is formed on one side with a projection, 3, encirclingthe aXle 2, and on the other with a circular recess, a, into whichprojects the inner half of a disk, 5, having a passage, 6, extendingdiametrically across the disk 5. In the passage are located slidingfriction-blocks 7, adapted to be moved outward from the center inopposite directions between frictionsprings 8, so as to bear against theperiphery of the circular recess 4:-

The blocks 7 are mounted on arms 9, projecting through slots 10 in thewall of passage G. The arms 9 are connected by pivoted bars 11 to asliding sleeve, 12, mounted on axle 2 and connected therewith by aspline, 13, engaging a groove in the sleeve. The lat ter is formed witha circular groove, 14:, in which are located the pins 15 on the end of aforked lever, 16, pivoted to the car-frame 17, and having aconnectingrod, 18, eccentric-ally pivoted to a disk, 19, and providedwith aver tical operating-lever, 20. By means of the foregoing-describedmechanism the sleeve 12 is permitted to turn with the axle 2 withoutaffecting the lever 16, and the blocks 7 can be moved in and out offrictional engagement with the disk 5, thereby serving as africtionbrakc. The lever is held in adjusted po' sition by means of apawl, 21., adapted to engage one of a series of notches, 22, inprojection 19, and operated by a rod, 23, pivoted to a spring-actuatedlever, 24, at the end of lever 20. Adjacent to disk 1 is a ring, 25,inclosing a coiled spring, 26, one end of which is secured to theprojection 3 and the other to the ring 25.

On the outside of ring is located a disk, 27, fitting loosely into thering and secured to shaft 2 and having a toothed periphery, 28, withwhich a pawl, 29, is normally held in en gagement by means of a spring,30, to hold the ring 25 from being turned backward by the force ofspring 26. IVhen the car-starter is not in use, disk 5, ring 25, spring26, and disk .27 turn in the same direction with shaft 2. The disk 1. isformed on its periphery with teeth 31, with which aspririg-actuatedpawl, 32, engages, and the ring 25 has a single tooth,33, facing in the opposite direction to teeth 31. In the car-frame 17 islocated a springactuated pin, 3 1, which is heldiii-engagement by itsspring with toot-h 33.

The pin 34 is connected bya cord, passin g through rin and secured tothe periphcry of disk 17, so that when the lever 20 is moved back torelease the friction-blocks 7 the pin 34 is drawn out of engagement withtooth The pin 3i has mount-ed thereon a bent arm, 36, extending throughguides 37 on the frame 17 and having a curved end, 38, which bearsagainst one end of pawl 29 to hold it against the tension of spring 30,out of engagement with teeth 23. Upon the pin 34 being released fromtooth the arm 35 is withdrawn from pawl 19, and the latter is thereuponthrown into engagement with teeth 28 by means of spring 30, therebyholding the ring from being revolved forward by IOO with teeth 28. Inthe revolution of the axle 2 the disk 1 rotates in the same directiontherewith and the teeth 31 slip past the pawl. 32. The ring 25 beingheld by pin 34, the spring 26 is thereby wound up. Upon the car beingbrought to a standstill the spring 20 will-be wound up and ready to actto move the car forward, it being .held from action by the pin 8i,holding ring 25, and the pawl 32, holding disk 1. To start the car, thelever 20 is moved back, which releases the frictionblocks 7 and the pin31 and throws pawl. 29 into engagement with teeth 28. The spring 26 isthereupon free to turn the axle 2 for ward and the car will be movedforward. The movement of the ear starter and brake may be regulated bythe adjustment of lever 20, by means of its pawl 21. being thrown intoand out of engagement with the different notches 22 in projection 19.

This invention, in addition to starting a car, is also useful inassisting the car over upgrades, as the spring 26 maybe utilizedsimilarly to its use in starting the car to propel the car up an ascent.

It will thus be seen that with a car starter,

and brake of this description a powerful and eifective means is providedfor readily stopping and starting a car and assisting it over upgrades.

Having thus described my invention, what I claim as new, and. desire tosecure by Letters Patent, is

1. A car starter and brake consisting of a toothed disk mounted on acar-axle, a pawl on the car-frame engaging the toothed disk, a secondtoothed disk mounted on the car-axle, a ring loosely mounted on thesecond toothed disk, located between the toothed disks and having aspring-aetuated pawl adapted to engage the second toothed disk, a coiledspring located within the ring and having one end secured thereto andthe other toihe first toothed disk, a spririg-actuated pin and arm on.the car-frame :ulapted to hold the ring from turning in the samedirection with first toothed disk, and holding the pawl of the ring outof engagement with second toothed disk, a sleeve movable lengthwise onthe car-axle and having slidingfriction-blocks adapted to engage thefirst toothed disk, and a lever mechanism for operating thering-engaging pin, the pawls of toothed disks and the friction-blocksand their disk on the axle, substantially as shown and described.
